[QUOTE="IvanLasston, post: 1485127, member: 145676"] Any Third Party apps - or any external drives? My computers will tend to do this when something won't let the computer sleep. For example there is an App called Jettison - that should eject all external drives when the machine goes to sleep - but since I have my iPhoto and iTunes library on an external drive - Jettison won't eject those drives - and the sleep fails. And actually - my machine behaves exactly as you describe - the screen goes blank but nothing works or it acts erratic when it comes back. I've taken to getting rid of jettison and manually ejecting drives. Otherwise - I would have started as you did - and clean out the insides. Did you follow ESD protection while replacing the drive? The other thing this sounds like is the creeping death of ESD damage. [/QUOTE]
